Well the top three hardest are Diamond, Sapphire and Ruby, and an easy way to remember is: red-white & blue stones! The hardness of a gemstone is measured on its place on Mohs scale of hardness. 10 on Mohs scale being the hardest known naturally occurring substance– and the honor goes to the diamond
Although the hardest natural stone on the planet is a diamond that is rated ten on the Mohs scale, granite is known as the most durable and hardest natural stone that is used in construction material and is measured six on Mohs scale.
The hardest mineral commonly found in granite is quartz, which is normally a somewhat translucent, white to grey colored mineral.
